I’m a big Sherlock Holmes fan too, since childhood. If you want to read some very funny parodies, try Robert L. Fish’s Schlock Homes stories, or the Warlock Holmes series by G. S. Denning.
I am a fan, also. I have the one-volume book, The Complete Sherlock Holmes, which has “all four novels and all fifty-six adventures”. It is a great book with a preface by Christpher Morley.
The best film adaptations are the Granada series which follow the novels and stories very closely. Jeremy Brett and David Burke ARE Holmes and Watson. Brett mastered all the mannerisms. The Watson character is not portrayed as a dim-wit as he was in earlier versions. I think you can find the series on You-Tube.
